If cuda headers are presented to nix in $out/include they are added to future gcc calls via a -isystem flag. However, cuda does not allow kernel calls from template function if these are located in system-headers. We thus move headers from $out/include to $out/usr_include and add a custom hook to add these headers via -I. 2014-06-23 14:11:34 +01:00			`addIncludePath () {`
